3 Inch Polonium Cube (Spark Plug Sample) Experiments Zinc is also one ofPolonium's atomic number is 84 and its symbol is Po. It is a rare and highly radioactive metal with no stable isotopes; its natural occurrence is limited to tiny traces of the fleeting polonium 210 (with a half life of 138 days) in uranium ores. Due to its intense radioactivity, which results in the radiolysis of chemical bonds and radioactive self heating, its chemistry has mostly been investigated on the trace scale.
